Gap vs. Lululemon: Gap (GPS+0.1%) is upgraded by Wells Fargo to Outperform from Market Perform, with the investment firm saying the retailer has under-appreciated growth opportunities. One of those revenue channels could be Athleta which is looking more and more like a serious challenger to Lululemon (LULU+0.1%), according to a number of retail analysts. In an anecdotal aside, SA notes Athleta opened a new store in a Midwest mall just two storefronts down from Lululemon.
